MDKSA-2005:124

Problem description

A previous zlib update (MDKSA-2005:112; CAN-2005-2096) fixed an overflow
flaw in the zlib program. While that update did indeed fix the reported
overflow issue, Markus Oberhumber discovered additional ways that a
specially-crafted compressed stream could trigger an overflow. An
attacker could create such a stream that would cause a linked
application to crash if opened by a user.
The updated packages are provided to protect against this flaw. The
Corporate Server 2.1 product is not affected by this vulnerability.
